For a population with a mean of u=72 and a standard deviation of o=10 what is the standard error of the distribution of sample means for each of the following sample sizes

For a sample of n=4
oM=

For a sample of n=25 scores
oM=

Respuesta :

Answer:

For a sample of n=4 , SE=5

For a sample of n=425, SE=2

Step-by-step explanation:

The standard error of the distribution is given by;

[tex] SE = \frac{ \sigma}{ \sqrt{n} } [/tex]

For a sample of n=4,

The standard error is:

[tex]SE = \frac{ 10}{ \sqrt{4} } = \frac{10}{2} = 5[/tex]

For a sample of n=25, the standard error is

[tex]SE = \frac{ 10}{ \sqrt{25} } = \frac{10}{5} = 2[/tex]
